JAMES WEBB SPACE TELESCOPE

This year marks the ninth year that I started posting this news series. It all started with the winter meeting of the American Astronomical Society in 2011 and continues to this day. In this episode, at a town hall held on the first day of AAS meeting, NASA program managers and scientists express confidence that the James Webb Space Telescope will launch as currently scheduled in March 2021. Also, I got more feedback from my JWST reporting, this time from the Public Affairs Office at NASA. #JWST #SpaceFanNews #AAS235 Watch Last 2 JWST Videos Here: https://www.youtube.com/watch?v=xeW37uKip1c https://www.youtube.com/watch?v=oUzp8tLiCCc Get Mova Globe Here: http://bit.ly/deepastronMOVAGlobes Read More Here: https://spacenews.com/jwst-remains-on-schedule-for-march-2021-launch/ https://spacenews.com/jwst-schedule-margin-shrinks/ Join our Chat on Discord here: https://discord.gg/nqGpvtK Like this content?

In this week's questions show, I tackle all the questions about James Webb generated by the videos we did this week. Can it be refueled? How can it see the entire sky? Is the delay a blessing? And more... 00:30 How will JWST run out of propellant? 03:12 Are there spacecraft that could service JWST? 05:00 Can JWST only see half the sky? 08:21 Is the delay a blessing in disguise? 10:58 Why not construct it in Low Earth Orbit? 13:09 Could we build a copy? 14:29 Could JWST use gravitational lensing? 15:55 Will JWST image black holes? 17:52 Is the telescope an antique? 18:49 Should we look or explore? 20:52 Could it find vegetation? 22:00 Is James Webb already a failure? Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week, and answer them here.

In October 2019, technicians and engineers successfully performed a critical test on NASA’s James Webb Space Telescope by fully deploying and properly tensioning each of its five uniquely sized sunshield layers, putting them into the same positions they will have in space. To observe distant parts of the universe humans have never seen before, the Webb observatory is equipped with an arsenal of revolutionary technologies, making it the most sophisticated and complex space science telescope ever created. Among the most challenging of these technologies is the five-layer sunshield, designed to protect the observatory's mirrors and scientific instruments from light and heat, primarily from the Sun. Due to the telescope’s size, shape and thermal performance requirements, the sunshield must be both big and complex. As if that’s not challenging enough, it also must be very lightweight, fit inside a standard 5-meter (16-foot) diameter rocket fairing, survive the perils of launch, and accurately deploy into its required shape, with only a single chance to get it right. Following Webb’s successful sunshield test within Northrop Grumman’s Redondo Beach, California facility, team members have begun the long process of perfectly folding the sunshield back into its stowed configuration for flight, which occupies a drastically smaller volume than when it is fully deployed. Webb will be the world's premier space science observatory. It will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international project led by NASA with its partners, ESA (European Space Agency), and the Canadian Space Agency.

Today I'll be joined by Paul Geithner, the Deputy Project Manager for NASA's James Webb Space Telescope. You've had questions about this mission. Well... now's your chance to get them answered directly from the source. Paul started working with NASA in 1991 on the Hubble Space Telescope, shifting over to James Webb. In 2011, he became the Deputy Project Manager, Technical for James Webb.

On March 30, 2021, NASA’s James Webb Space Telescope will blast off from the European Space Agency’s European spaceport in Kourou, French Giana on board an Ariane 5 rocket. It’ll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, it’ll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos. Over the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets. And if you listened to the words I just said with equal parts terror and skepticism, I don’t blame you. James Webb’s path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment. So today, I want to do a deep dive into James Webb. To talk about the history of the mission, why it exists, how the development went, and where it stands today. I’ll warn you though, the length of this video is going to go way over budget.

The Hubble Space Telescope has given us some of the most amazing views of the universe for 25 years and although it could go on for many years more, things are starting to go wrong but without the shuttle, we have no real way the fix it. But its successor the James Webb Space Telescope was due to have been in space years ago. However, now it isn't due to launch until 2021, so could we save Hubble and why is the JWST taking so long.

NASA’s James Webb Space Telescope has been delayed yet again. Gizmodo reports NASA has moved the target launch from May 2020 to March 2021. The telescope has been plagued by delays and budget increases since its inception in 1996. An independent review in April 2018 found five kinds of problems, including human errors, “embedded” problems not identified during testing, lack of experience, excessive optimism, and the system complexity. The latest delay will add $800 million to the telescope’s development cost. It is expected to launch in 2021. https://gizmodo.com/nasa-delays-james-webb-space-telescope-yet-again-commi-1827177557 http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate, and John Mather, senior project scientist, comment on an independent review board’s findings on the agency’s James Webb Space Telescope. Webb is now targeting March 2021 as a new launch date, after the board assessed delays in integration and testing. NASA and the board unanimously agree that Webb can still achieve mission success.

The James Webb Space Telescope will be the largest telescope ever sent into space. It is the result of efforts from NASA, the European Space Agency and the Canadian Space Agency and will peer to the edges of the visible universe. This video highlights some of the Webb’s most impressive facts.

The Hubble Space Telescope has been in space for 28 years, producing some of the most beautiful and scientifically important images of the cosmos that humanity has ever taken. But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer. NASA’s James Webb Space Telescope is in the final stages of testing, and WFIRST is waiting in the wings. You’ll be glad to know there are even more space telescopes in the works, a set of four powerful instruments in design right now, which will be part of the next Decadal Survey, and helping to answer the most fundamental questions about the cosmos.

In this week's questions show, I wonder if the James Webb Space Telescope will be able to find satellites around other stars, what my favorite sci-fi FTL method is, and why can't we see Mars as a bright object in the sky?

Love the channel. 🙂 Will the James Webb Telescope be able to see evidence of artificial satellites around exo-planets, should any exist? Would there be a certain size or composition requirement for JWT to spot them? And how awesome would that be?! 🙂 Matt Gibson Fraser, if you could pick any FTL travel method from any show or movie and have it be a reality and give it to humanity, which would you pick? Some examples include Elite Dangerous, Star Wars, Star Trek, Battlestar Galactica, Star Gate... ect... Cherotal Hey Fraser, I have a question about the birth of solar systems. If there is less mass in the gas cloud which collapse to a star system it will form a red or brown dwarf. Is it possible that a gas cloud with very little mass collapse and form a star system where the central body didn't light up? Will these "no-star" systems send out any radiation or light we can measure? Thanks in advance and thanks for all the great video content. Ed Chartrand I’m fascinated by the images depicted in films such as Star Wars where characters look up into space on far off planets where there are multiple moons practically filling the sky or one moon that is massively larger than what our moon appears in reality here on earth. Are these types of visuals actually possible on planets from a physics perspective? Can a moon be so close to a planet that it takes up that much of the sky and yet still have a stable orbit? Michael K I thought the ISS has some micro-meteorite protection and doesn’t just trust in pure luck? Jim Becker Fraser, I was just looking at a photo released by NASA from the Curiosity Rover which "includes Earth as the brightest point of light in the night sky". So why can we seem to be able to see Earth from Mars but can't see Mars from Earth with the same ease ?? DrewLSsix Could a hobby level astronomer benefit from combining two decent smaller telescopes to make an effectively larger binocular telescope? Like two one hundred ish mm combined into an effective two hundred ish unit? I ask because you can buy a pair of the smaller units for a couple hundred.... while a 200+mm scope is many many times more expensive! Flynn Bryant Hey Fraser, my question is, what is the criteria for questions that you answer in the comments compared to those which you select for your videos? Thanks for the tremendous effort you put in! Izuriel Palanayukei Hi Fraser! I've heard you mention books in passing before. Do you have a list of sci-fi books you recommend? Like Seveneves by Neal Stephenson or EON by Greg Bear? Big ole' sci-fi novels with or without aliens! Thanks! - Izu Scot Washburn Why couldn’t we use lasers to push the orbiting debris out of earth orbit? Seth McKay Hey Fraser! Your production schedule looks to be quite full with universe today, guide to space, Q&A, astronomy cast, etc (not to mention spending time with family). How do you organize and stay on schedule? Seems like you have would have to be really organized to stay on schedule as well as not end up working all day. I also have several different hats and need to organize better. Guest Question: Stefán Atli Þorvaldsson how can i become an astronaut if i am not from a big country like the USA, Russia or the EU

Engineers at NASA's Johnson Space Center in Houston spun NASA's James Webb Space Telescope around like a record on Jan. 10, 2018, before orienting it in a horizontal position in preparation for its upcoming move to Northrop Grumman in California.

Webb in Three Acts: The Telescope, The Science, The Legacy Klaus Pontoppidan, Bonnie Meinke, and Alexandra Lockwood, Space Telescope Science Institute NASA’s James Webb Space Telescope is expected to launch in spring 2019 and will be the premier infrared space observatory of the next decade. It promises to observe everything from planets in our solar system to galaxies over 13 billion light years away. With the Science and Operations Center of this Great Observatory right here at the Space Telescope Science Institute, Baltimore will continue and grow as a hub for exciting scientific discovery and innovation. Come find out about what we’re doing, how we’re doing it, and who is doing it in this overview of the Webb Mission. Host: Dr. Frank Summers Recorded live on January 16, 2018 at the Space Telescope Science Institute in Baltimore, MD USA For more information: http://hubblesite.org/about_us/public_talks/

This 360 video was taken before NASA's James Webb Space Telescope left NASA's Goddard Space Flight Center in Greenbelt, Maryland, in May 2017. Look around to see engineers at work inside the cleanroom, and for several plaques with information about the cleanroom and about Webb telescope!

As many of you know who’ve been following SFN for a while know that this video series was started in January 2011 during the winter meeting of the American Astronomical Society. Well this week finished the one for 2018 and here is a roundup of stories I found most interesting. The people with the American Astronomical Society call their winter meeting the Superbowl of Astronomy and while that may be a bit hyperbolic, it is an exciting time for astronomers. They get to announce some of their most exciting work during this meeting and while I have been to several, lately I’ve had to watch them from afar. But I do hope to start live streaming from them again one day. So in the spirit of SFN, I’m going to give you a brief roundup of some of the latest research that came out this week from the world of professional astronomers from around the world. There was so much released this week that there is no way I can cover all of it in a 10 minute or so video, so I’m keeping it to those things I found most interesting.

Members of the media were invited to NASA’s Johnson Space Center in Houston on Jan. 10, to hear about the results of recent cryogenic vacuum tests on the James Webb Space Telescope, and the next steps on the observatory’s path to space. Webb was tested as a complete optical system in Chamber A at Johnson, which mimics the space environment the telescope will experience during its mission. Built in 1965 to conduct thermal-vacuum testing on the Apollo command and service modules, Chamber A is the largest structure of its kind in the world and is a listed National Historic Landmark. The James Webb Space Telescope is the world’s premier infrared space observatory of the next decade. Webb will help to solve mysteries of our solar system, look to distant worlds orbiting other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, the ESA (European Space Agency) and the Canadian Space Agency.

P. Ferruit - ESA In anticipation of the first JWST Call for proposals in late November 2017, the European Space Agency is organizing a series of workshops to engage and inform the astronomical community. The first workshop held at ESA's European Space Astonomy Centre (ESAC) in Madid, Spain, 4-6 October 2017, showcased the capabilities of the JWST science instruments, their observing modes and expected in-orbit performance. The main goal of this second workshop was to provide ample hands-on experience with the various tools supporting preparation and submission of proposals. Among them the Target Visibility Tool, the Exposure Time Calculator and the Astronomy Proposal tool (APT).

About 1 million miles away from the nearest eye surgeon, NASA’s James Webb Space Telescope will be able to perfect its own vision while in orbit. Though the Webb telescope will focus on stars and galaxies approximately 13.5 billion light-years away, its sight goes through a similar process as you would if you underwent laser vision correction surgery to be able to focus on an object 10 feet across the room. In orbit at Earth’s second Lagrange point (L2), far from the help of a terrestrial doctor, Webb will use its near-infrared camera (NIRCam) instrument to help align its primary mirror segments about 40 days after launch, once they have unfolded from their unaligned stowed position and cooled to their operating temperatures. Laser vision correction surgery reshapes the cornea of the eye to remove imperfections that cause vision problems like nearsightedness. The cornea is the surface of the eye; it helps focus rays of light on the retina at the back of the eye, and though it appears to be uniform and smooth, it can be misshapen and pockmarked with dents, dimples, and other imperfections that can affect a person’s sight. The relative positioning of Webb’s primary mirror segments after launch will be the equivalent of these corneal imperfections, and engineers on Earth will need to make corrections to the mirrors’ positions to bring them into alignment, ensuring they will produce sharp, focused images.
